Biological bases for whitebait culture Galaxias maculatus (Jenyns, 1842): a review

Latin American Journal of Aquatic Research, 2017
Galaxias maculatus (Jenyns, 1842), is a gourmet fish of great commercial importance with overexploited fisheries. So, studies of its biology are essential in order to develop a technology for its cultivation (galaxiculture), which is at a pilot stage. The goals of this work are: 1) to provide a synthesis of the literature information on the biology of ...

Habitat-use strategies of young barramundi (Lates calcarifer) in a heavily modified landscape. [PDF]

J Fish Biol
Abstract Barramundi (Lates calcarifer) is a facultatively catadromous species that migrates between saltwater and fresh water to complete its life cycle. Modified riverine landscapes may limit these migratory paths and alter the environmental cues that migratory fish rely on to trigger migration.

An Updating of Withebait Farming (Galaxias maculatus) in Chile [PDF]

, 2012
The withebait Galaxias maculatus is an endemic species from Argentina and Chile (Cussac et al., 2004), and it is important in ecological webs in Argentinean and Chilean inland waters (Soto & Zuniga, 1991; Soto et al., 1994; Modenutti et al., 1998). This species has a maximum size of 17 cm and its migratory juvenile stage is transparent or “crystalline”

Egg cannibalism by inanga (Galaxias maculatus) [PDF]

New Zealand Journal of Marine and Freshwater Research, 2003
Abstract Egg cannibalism by inanga (Galaxias maculatus) was found to occur immediately after spawning. Spent and immature inanga from a school of 335 fish consumed between 0 and 51 eggs each. As inanga spawning sites are high on the river bank and only accessible on high spring tides, further opportunities for egg predation are limited to when the eggs

Interactions Between Non-Native Western Mosquitofish and Native Bluegill Sunfish: Mesocosm Experiments. [PDF]

Ecol Evol
Native Bluegill Sunfish had important competitive impacts on invasive Western Mosquitofish and also had intraguild predation effects that prevented successful recruitment of Western Mosquitofish. In contrast, Bluegill Sunfish were affected by intraspecific effects more than by interspecific effects from Western Mosquitofish.

Fishways provide catchment-scale improvements to common galaxias ( Galaxias maculatus ) upstream of a barrier in south-eastern Australia

New Zealand Journal of Marine and Freshwater Research, 2023
The common occurrence of dams is a major threat to riverine fish communities globally and a common remediation technique for fragmented fish communities is fishway construction. Demonstrating the effectiveness of this technique on impacted species is required to rationalise or improve management practices.

Assessment of Heavy Metal Contamination in Two Edible Fish Species and Water from North Patagonia Estuary

Applied Sciences, 2021
Estuaries worldwide have been severely degraded and become reservoirs for many types of pollutants, such as heavy metals. This study investigated the levels of Cd, Cu, Mn, Ni, Pb, and Zn in water and whole fish.

A Global Assessment of Parasite Diversity in Galaxiid Fishes

Diversity, 2021
Free-living species often receive greater conservation attention than the parasites they support, with parasite conservation often being hindered by a lack of parasite biodiversity knowledge.

Attraction of migratory inanga (Galaxias maculatus) and koaro (Galaxias brevipinnis) juveniles to adult galaxiid odours [PDF]

New Zealand Journal of Marine and Freshwater Research, 2003
The response of migratory galaxiid juveniles, inanga (Galaxias maculatus) and koaro (G. brevipinnis), to the odours of adult galaxiids was tested in a two-choice chamber apparatus. Both conspecific and heterospecific odours were tested. Inanga juveniles were attracted to adult inanga (G. maculatus), banded kokopu (G.
